Tamron M23FM 

Ultra high-performance C-mount lenses for 2/3" sensors

With a pixel pitch of just 2.5 microns, the M23FM lens series offers ultra-high resolution with minimal distortion. The minimum object distance (MOD) is only 100 mm for the focal lengths of 6 mm up to 25 mm and 150 mm for the f=35 and 50 mm lenses. As usual with Tamrons industrial line up, these lenses offer locking screws for focus and aperture.

The operating temperature from -10°C up to +70°C is another outstanding feature which makes this series the perfect choice, when it comes to rough environmental conditions with high resolution demands.
